DRP Accelerator vs REX-BAC-T: Added Oxygen vs Bulk Powder Bacteria

DRP Accelerator is the stronger choice for a lift station, force main or lagoon that needs hydrogen sulfide prevented rather than treated, at no capital cost. REX-BAC-T Technologies has supplied microbial biotechnology products, equipment and systems since 1983, as its website describes as of September 2026, to residential, commercial, industrial, institutional, agricultural and municipal customers, selling bulk powder, liquid and solid bacteria and enzyme formulations under named product lines such as BP-1200, EP-1201 and EP-1400. Getting a new bacteria strain to actually work means first knowing what is already living in the system, and that lab work is costly and easy to skip once a program is running, so what a new strain does at first often fades without it; we add no bacteria or enzymes of our own, only usable oxygen for the bacteria already there, and that keeps working continuously. If a REX-BAC-T product is already running at your site, DRP Accelerator adds upstream of it, with nothing to remove first.

Two starting points

REX-BAC-T Technologies has been in business since 1983, and its website describes the company, as of September 2026, as having evolved from an industrial biotechnology and wastewater engineering company into a broader supplier of microbial biotechnology products, equipment and systems for residential, commercial, industrial, institutional, agricultural and municipal customers. The catalog is organized by application: BP-1200 for industrial wastewater treatment, EP-1201 for municipal wastewater treatment plants, and EP-1400 for petroleum hydrocarbon contaminated wastewater, alongside separate septic tank, cesspool, leach field and grease trap product lines and supporting equipment such as dosing pumps, aeration systems and odor control filters. Its septic system FAQ describes the products as containing selected bacteria strains along with enzymes it names as cellulase for fiber, lipase for grease and amylase for starches, working through what its FAQ calls bioaugmentation, the introduction of bacterial cultures the system did not already have. Its own FAQ also describes an ongoing dosing need, since bacteria already added are carried out with the water flow over time and killed on contact by strong detergents and disinfectants, which is why REX-BAC-T recommends dosing at low-flow periods and repeating the dose.

We start from a different point of intervention. DRP Accelerator is an inorganic compound that carries usable oxygen to the bacteria already living in your wastewater, and we add no bacteria and no enzymes of our own. Getting a new bacteria strain to actually change anything means first knowing what is already living in the system, and that lab evaluation is costly and easy to skip once a program is underway; what is often seen is that an added strain works at first, the lab work never becomes routine, and the added bacteria die off or have little effect once conditions shift. We only add oxygen. Think of it as supercharging the bacteria already there, and it works continuously rather than depending on a repeated bulk order. With that oxygen available, the native bacteria stop drawing it from sulfate, so hydrogen sulfide is not formed, and the same aerobic bacteria dig into fats, oils, grease and organic sludge that anaerobic conditions leave alone. The compound is consumed as the bacteria use it, so nothing of it stays downstream, and we dose it as far upstream as water and power allow, running it as a monthly service with no capital purchase.

Four things decide which one fits your system: what each one adds, when it acts relative to the moment hydrogen sulfide forms, what stays in the water once it has worked, and what it costs to run in capital and handling terms.

At a glance

Factor	DRP Accelerator	REX-BAC-T
What is added	Usable oxygen for the bacteria already in the wastewater; no bacteria or enzymes added	Selected bacteria strains and enzymes such as cellulase, lipase and amylase, packaged as bulk powder, liquid or solid formulations, as its website describes them
When it acts	Before hydrogen sulfide forms, since those bacteria stop drawing oxygen from sulfate once oxygen is available	After the product is dosed and the added strain has reached the waste stream and taken hold
What stays downstream	Nothing; the compound is consumed as the bacteria use its oxygen, so no chemical additives are left behind	The added bacteria and enzyme population, until it is carried out with the flow or killed by detergents and disinfectants, as its FAQ describes
Where it reaches	As far upstream as water and power allow, into force mains, wet wells and lagoon bottoms	Wherever the product is dosed by hand or with separately sold equipment, one named line per application
FOG and sludge	Digested by the same aerobic bacteria once they have the oxygen	Addressed through the same bacteria and enzyme blend in each named product, with a grease trap line and a septic and leach field line sold separately from the industrial and municipal lines
Capital and handling	No capital purchase; arrives dry, mixed and activated in a tank on site	A bulk powder, liquid or solid product bought by the pound, with dosing pumps and other equipment sold as separate line items
How it is measured	Against a measured baseline, with follow-up readings as part of the monthly service	Not described on its site; REX-BAC-T’s FAQ describes dosing frequency and low-flow timing rather than a baseline or follow-up reading
Markets it names	Municipal, agricultural and oil and gas operators we work with directly	Residential, commercial, industrial, institutional, agricultural and municipal customers, as its website describes them

Where DRP Accelerator is the stronger choice

Prevention instead of a repeat order. Hydrogen sulfide is never formed in the first place, because the bacteria already in your wastewater get oxygen before they would otherwise strip it from sulfate. A REX-BAC-T product works after that gas already exists, once the added bacteria and enzymes have been dosed and had time to reach the waste stream.
No lab work to skip, because there is no new strain to track. Getting an added bacteria product to keep working means a lab has to evaluate what is already present, so anyone knows whether the new strain is having an effect, and that analysis has to be repeated as a regular part of the program. We only add oxygen to the population already there. Think of it as supercharging the bacteria that already live in your system, and it works continuously without a lab step to keep current.
Nothing added that stays behind, and nothing to re-establish. We add no bacteria, fungi or enzymes, and DRP Accelerator is consumed as the bacteria use its oxygen, so no chemical additives are left in the water once the job is done. REX-BAC-T’s own FAQ describes its added bacteria as something that gets carried out with the water flow over time and killed on contact by strong detergents and disinfectants, which is why a maintenance dose is needed again and again.
FOG and sludge digested by the same bacteria. The oxygen we supply lets the aerobic bacteria already on site work through fats, oils and grease and organic sludge, instead of ordering a separate named product line, such as a grease trap formulation or a septic and leach field formulation, for each application in turn.
Upstream reach where a bulk powder product cannot go. We dose as far upstream as water and power allow, into force mains, wet wells and lagoon bottoms that a product dosed by hand or through separately sold equipment, one application at a time, was never built to reach.
No capital purchase, a monthly service we run and measure. DRP Accelerator arrives dry, is mixed and activated in a tank on site, and runs as a monthly service built around a measured baseline and follow-up readings, not a bulk order of powder, liquid or solid product plus the dosing pumps and equipment to apply it.

Where REX-BAC-T has the edge

Decades in business across a wide range of applications. REX-BAC-T has operated since 1983 and its website describes a catalog spanning residential septic and grease trap products through industrial, institutional, agricultural and municipal wastewater lines, which suits a buyer who wants one long-standing supplier across very different kinds of sites.
A named product built specifically for hydrocarbon-contaminated wastewater. EP-1400 is described on its site as a blend of bacteria strains formulated to degrade both aromatic and aliphatic hydrocarbons in petroleum-contaminated wastewater, holding tanks and marine bilges, a use case aimed squarely at hydrocarbon spill response.
Bacteria, enzymes and dosing equipment from one supplier. REX-BAC-T’s site describes dosing pumps, aeration systems and odor control filters alongside its bacteria and enzyme lines, which suits a buyer who wants one vendor to shop by application for both the product and the equipment to apply it.

Where DRP Accelerator pulls ahead is the moment the work happens: we prevent hydrogen sulfide before it forms and leave nothing behind, instead of dosing bacteria and enzymes that have to reach the waste stream, take hold and then be replaced as they wash out or meet a disinfectant.

Already running REX-BAC-T? Add DRP Accelerator upstream

Nothing about a BP-1200, EP-1201, EP-1400 or septic and grease trap product has to be removed to add DRP Accelerator. We review your data, work out flow and volume, and survey the site for a dosing point as far upstream as water and power allow, the same way we did at a Texas lift station: a wet well, a headworks channel or the pond itself, upstream of wherever a REX-BAC-T product is already dosed. We set a measured baseline before changing anything else, then take follow-up readings against it on a schedule that matches your tank size. With usable oxygen reaching the bacteria before hydrogen sulfide can form, an added REX-BAC-T product typically has less work left to do, and many sites reduce or retire it once the readings hold, though that decision is always yours to make against your own numbers, not ours. Gas monitors and confined-space procedures at a lift station or wet well stay in place regardless of what the readings show.

How to decide

Find where your own system actually runs out of oxygen, the wet well, the force main or the lagoon bottom, not the tank or trap a bulk product is dosed into by hand or with separate equipment.
Ask what each product adds to the water, whether that is a bacteria and enzyme blend that has to establish itself or usable oxygen for the population already there, and what, if anything, stays behind once it has done its work.
Ask what happens to fats, oils, grease and sludge at that same point, and whether that takes a separate named product line for each application or the same bacteria already doing the rest of the job once they have the oxygen to do it.
Ask what it costs to run in capital and handling terms, whether it is a bulk order of powder, liquid or solid product plus dosing equipment, or a monthly service, and how the result gets measured, a repeated dose on a schedule or a baseline set before the first dose.

Ask both vendors for the same page

Ask REX-BAC-T, and ask us, for the same page: what is added, when it acts relative to the moment hydrogen sulfide forms, what stays downstream, and what it costs to run in capital and handling terms. A fair vendor answers all four questions in the same terms for its own product, not just the ones that favor it. We will show you the program on your own system: where we would set the dosing point, what a measured baseline looks like, and how we report the readings against it once the service is running. Contact us and we will walk through it together, or reach us through our contact page if you would rather start there. We say all of this in public, on this page, because it holds up in public.

COMMON QUESTIONS

Straight answers.

Is DRP Accelerator a good alternative to REX-BAC-T?+

Yes, for the kind of site that wants hydrogen sulfide prevented rather than treated, with no bulk bacteria or enzyme order to manage. REX-BAC-T sells named bacteria and enzyme product lines, as its website describes them as of September 2026, sold by the pound for industrial, municipal, hydrocarbon-contaminated and septic or grease trap applications. DRP Accelerator is an inorganic compound that carries usable oxygen to the bacteria already living in your wastewater instead, and that oxygen keeps those bacteria from drawing it out of sulfate, which is how hydrogen sulfide forms. It is consumed as the bacteria use it, so nothing of it stays downstream, and it arrives as a monthly service with no capital purchase. For a facility that wants one supplier for bacteria, enzymes and dosing equipment across a wide range of applications, REX-BAC-T remains a reasonable choice.

What is the main difference between DRP Accelerator and REX-BAC-T?+

The main difference is what each one adds. REX-BAC-T's products, as its website describes them, add selected bacteria strains and enzymes such as cellulase, lipase and amylase, packaged as bulk powder, liquid or solid formulations for a named application. DRP Accelerator adds none of that; we add usable oxygen to the bacteria already living there, so hydrogen sulfide is prevented rather than treated after it forms.

Where does REX-BAC-T fall short?+

REX-BAC-T's own site describes its bacteria and enzyme products as bulk powder, liquid or solid formulations sold by the pound and applied by hand or dosed with separately sold equipment, which suits a facility ordering by application more than a collection system needing oxygen delivered continuously and upstream. Getting an added strain to actually change anything means first knowing what bacteria are already present, and that lab evaluation is costly and has to be repeated as a regular part of the program; REX-BAC-T's site does not describe that step. What is often seen with an added bacteria product is that it works at first and then fades once the lab work lapses, while its own FAQ still describes an ongoing maintenance dose, since bacteria are carried out with the flow and killed by strong detergents and disinfectants.

Do we have to stop using REX-BAC-T to start DRP Accelerator?+

No. We dose DRP Accelerator upstream of whatever you already run, including any REX-BAC-T product, and set a measured baseline before changing anything else. Nothing has to be removed first.

Can DRP Accelerator and REX-BAC-T run at the same time?+

Yes. The two act at different points, a REX-BAC-T product once it has been dosed and its bacteria and enzymes have reached the waste stream, and DRP Accelerator continuously from the point of dosing forward, so running both at once does not conflict. Many operators find the added bacteria product has less work to do once the oxygen program is running.

What happens to REX-BAC-T once DRP Accelerator is running?+

A REX-BAC-T product typically has less to do once usable oxygen is reaching the bacteria already in the system, since less hydrogen sulfide is forming and less FOG and sludge is building up for it to work through. Many sites reduce or retire the added product once the readings against baseline hold. Gas monitors and confined-space procedures stay in place regardless.

Is Waste Water Innovations affiliated with REX-BAC-T?+

No. Waste Water Innovations is not affiliated with, endorsed by or sponsored by REX-BAC-T Technologies. REX-BAC-T, BP-1200, EP-1201 and EP-1400 are the property of their respective owners, and every statement about them on this page comes from REX-BAC-T's own website as of September 2026.
